Abstract

In order to determine the region of glass formation between the AsS and ErS compounds, we studied the methods of physicochemical analysis: differential thermal (DTA), X-ray phase (XRD), microstructural (MCA), as well as by measuring microhardness and density. The eutectic composition between the AsS and ErS compounds is 10 mol. % ErS and temperature 280oC. At a cooling rate v = 102 K / min, the glass transition region based on AsS reaches 10 mol. % ErS. Some physicochemical properties of alloys from the region of glass formation have been investigated. The area of homogeneity based on AsS reaches up to 1.5 mol. % ErS.

Summary

Бакинский Государственный Университет

С целью определения области стеклообразования между соединениями AsS и ErS исследованы методами физико-химического анализа: дифференциально-термического (ДТА), рентгенофазового (РФА), микроструктурного (MСA), а также путем измерения микротвердости и плотности. Эвтектический состав между соединениями AsS и ErS составляет 10 мол. При скорости охлаждения v=102 град/мин область стеклования на основе AsS достигает 10 мол. Исследованы некоторые физикохимические свойства сплавов из области стеклообразования. Область гомогенности на основе AsS достигает до
